Interoperability of the BIS - Grid Workflow Engine with Globus Toolkit 4

چکیده
In the D-Grid project BIS-Grid we developed the BIS-Grid Workflow Engine in order to utilize a common WS-BPEL workflow engine for scientific workflow execution in WSRF-based Grid infrastructures. The BIS-Grid Workflow Engine itself is built on the Grid middleware UNICORE 6 to benefit from its security mechanisms and to automatically gain interoperability with UNICORE 6-based Grid infrastructures. As beside UNICORE 6 the Grid middleware Globus Toolkit 4 is prevalent in the D-Grid infrastructure, we decided to examine the interoperability of the BIS-Grid Workflow Engine with Globus Toolkit 4. The interoperability with Globus Toolkit 4 concerns basically the support of its Grid Security Infrastructure (GSI) by UNICORE 6. In this paper we describe to what extend GSI is already supported by UNICORE 6 and what is missing. We furthermore give some details about our implementation for the BIS-Grid Workflow Engine to allow Globus Toolkit 4 service invocations within a WS-BPEL workflow execution.

To achieve this goal, we dev...
متن کاملA Light-Weight Grid Workflow Execution Engine Enabling Client and Middleware Independence
We present a generic and light-weight Grid workflow execution engine made available as a Grid service. A long-term goal is to facilitate the rapid development of application-oriented end-user workflow tools, while providing a high degree of Grid middleware-independence. The workflow engine is designed for workflow execution, independent of client tools for workflow definition. A flexible plugin...
متن کاملMSF: A Workflow Service Infrastructure for Computational Grid Environments
Globus has become a standard in the construction of Grid computing environments. However, it still needs more work and research to satisfy requirements from various grid applications such as workflow services. We propose a Meta Scheduling Framework (MSF) for workflow service management based on the Globus toolkit. The MSF provides an XML-based Job Control Markup Language (JCML) for describing i...

In this paper we propose a Grid Workflow Infrastructure, which serves as the base for specifying and executing collaborative interactive workflows within computational grids. The infrastructure is based on the Open Grid Services Architecture (OGSA) and leverages the concepts of the Business Process Execution Language for Web Services (BPEL4WS). Using OGSA enables us to exploit advanced Grid fea...
